ALFRED JEFFERY, OF PHILADELPHIA, PENNSYLVANIA.

PENCIL-CASE.

SPECIFICATION forming part of Letters Patent No. 460,971, dated October13, 1891.

Serial No. 384,830. (No model.)

T0, @ZZ whom, it may concern:

Be it known that I, ALFRED JEFFERY, of the cit-y of Philadelphia, andState of Pennsylvania, have invented a certain new and'usefulImprovement in Pencil-Cases; and I do hereby declare the following to bea full, clear, and exact description thereof, reference being had to theaccompanying drawings, forming part of this specification.

My invention has relation to pencil-holders or pencilcases; and itconsists in a case or holder for a removable lead, having a channelprovided for the said lead, and a removable adjustable end piece, andpacking or cushion of rubber or othersuitable material for biliding uponand securing the lead in position in the case when compressed, ashereinafter more particularly described. Y l The object of my inventonis to provide a pencil-case for adjustable lead, which will iirmlysecure the lead in any desired position in a manner which will preventthe lead from the liability of breaking off by reason of the nippingdevice provided in the case for securing the lead in position, as innumerous devices heretofore invented, and to produce a device whichshall .at the same time more securely and satisfactorily hold the leadin any desired position in the case.

In the accompanying drawings similar letters of reference refer tosimilar parts throughout.

Figure lis alongitudinal sectional view of myimproved pencil-case. Fig.2 is a sectional view of the point or end securing device, in detail,coupled to the barrel or case. Fig. 3 is a detail View of the portion ofthe point, showing the rubber paekingor cushion compressed and bindingupon the lead. Fig. 4 is a crosssectional view on the line x of Fig. 2.Fig. 5 is a cross-sectional view on the line g/ y of Fig. 2. Fig. 6 is across-sectional view on the line .es of Fig 2. Fig. 7 shows the packingor cushion detached from the point or tip of the case.

A represents the barrel or case of the pencil, which is providedcentrally with a longitudinal tubular sheath l), which holds andprotects the lead 1'. A plug c is fitted within the barrel A at or nearthe lower end and firmly attached thereto7 the plug c having providedupon its lower projecting end the screw-thread, to which the hollow tipor point d, also provided with a corresponding screwthread cut on itsinterior atthe base, is screwed and adjusted, the base of the tip orpoint d being preferably of a diameter externally about equal to theinternal diameter of the barrel A, so as to pass freely into the latter.The sheath h is provided, preferably, with a collar or expansion ofmaterial e outside of the plug '6, so as to form a shoulder e with theplug c. A collar k is also provided on the outer end of the sheath of adiameter about equal to that of the interior diameter of the tip orpoint cl at that point, the said sheath b extending, preferably, withinthe tip or point d, leaving only sufficient space between the end of thetip d and the shoulder k to provide for the packing or cushion j", ofrubber or other suitable elastic material. The packing or cushionfis ofa diameter about equal to the diameter of the end of the tip CZ, and isprovided with a cylindrical hole through its central portion slightlylarger than the diameter of the lead t', through which the said lead t'passes. The diameter of the orifice 0, provided in the end of the tip(Z, is also preferably slightly larger than the diameter of the lead z'.The interior diameter of the sheath l) is also slightly larger than thediameter of the lead. The sheath b should lit neatly in the orificeprovided for its passage in the plug e and in line with the axis of thecase, and the surface between the sheath b and the plug cmaking a smoothjoint, allowing ofthe sheath b to rotate within `the plug c with the tip(I and the lead c' when the packing f is compressed against the shoulder71'..

In inserting the lead for use the point d is partially unscrewed, so asto release the compression of the packing or cushion f' and to allow thelead /L' to be inserted in the sheath l), leaving a sufficient point ofthe lead proj ecting. As the point or tip d is then screwed up on theplug c, the packing or cushioufis necessarily compressed between thepoint of the tip d and the shoulder 7.3, provided on the end of thesheath b,'which binds necessarily upon the lead t' and holds it securelyin position. The collare, forming the shoulder c', prevents the sheathb, when the compression occurs, from being forced up into thecase,though free to rotate with the tip, packing or cushion,

TOO

and lead. If the sheath is not free to rotate with the lead and packing,a twisting and displacement of the packing might occur and tend tostrain or break the lead. The sheath b might be retained in its positionand prevented from being forced in by other construction-such, forinstance, as extending the sheath to the extreme upper end of the caseA-and yet be free to rotate, though the construction I have described isa preferable one.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

1. In a pencil-case, a main barrel and adjustable point or tipadjustably secured to said barrel provided therein, a longitudinalsheath having a channel for the reception of the lead, said sheath adjusted rotatively Within said barrel and extended into said removableadjustable tip, an elastic packing or cushion provided in said tipbetween the end of the saine and the end of said sheath, and an orificeprovided in said packing for the passage of the lead, said packingadapted to be compressed upon the lead by adjustlnent of the removabletip upon the barrel, substantially as described.

2. A pencil-case, having a barrel A, removable adjustable tip d,longitudinal sheath b, provided with collars e and 7c, plug` c, securedin said barrel, and packing f, substantially as described.

3. In a pencil-case, abarrel A, longitudinal sheath b, having collars eand k, said sheath adapted to rotate in said barrel, plug c, andadjustable tip d, packing f, provided in said tip, and lead i,substantially as described.

In Witness whereof I have hereunto set my hand this 9th day of March, A.D. 1891.

ALFRED JEFFERY.
